CROSS REFERENCE TO RELATED APPLICATION

The present invention claims the priority of Hong Kong Short-term Patent Application No. 11107563.9 as submitted on 20 Jul. 2011.

TECHNICAL FIELD

The present invention relates to a public cemetery, and more particularly to a modern green environmental public cemetery complex.

BACKGROUND OF THE INVENTION

Traditional burial is very common in China and worldwide. As population increasing, development of city and cemetery are limited by land resources. At present, a permanent cemetery in Hong Kong might cost about four to five hundred thousand dollars, and it is not definitely available. To avoid cremation, some elderly in Hong Kong even make a deposit of over ten hundred thousand Hong Kong dollars for a permanent cemetery in ShenZhen, China. A traditional burial cemetery provided by Hong Kong Government costs around a few thousand Hong Kong dollars only, but the bones must be taken out for re-burial or cremation after six years. In 1999, some cemetery management staffs have even been prosecuted since they have illegally reserved some cemeteries for personal use which are originally reserved for civil servants who died at their posts.

For example in Hong Kong, most of the burial cemeteries are built on hillsides, and there are large scale traditional burial cemeteries located in Happy Valley, Chai Wan, Aberdeen and Pokfulam etc. on the small Hong Kong Island. But, who would like to live beside these hundreds of old and new tombstones of burial cemeteries? Furthermore, insufficiency of niches has occasionally become a headline news. In addition, there are six crematoriums in Hong Kong such a small city, wherein the actual area of a crematorium is much larger than its floorage, because commercial and residential buildings will not likely be built nearby.

The defects of the present public burial and cremation policies:

Based on the external social costs (negative externalities) of cremation, and the reduced external social benefit (positive externalities) of burial based on the substitution of burial by cremation, the Government should relocate the current resources from cremation to green environmental burial which solves land occupying problem of burial. The charge of cremation should reflect the overall social costs. The Government should relocate the resources and formulate additional policies to support new burial since it can be developing in a sustainable manner, and to help acquirement of resources from international carbon trading market.

The external social costs of cremation:

1) The high temperature in cremation and the burning of thousands organic substances will affect the surrounding environment and accelerate global warming;

2) The exhaust emissions of cremation will cause air-pollution and have deep impact of damaging the ecology and atmosphere (Remarks: Any kind of standard of exhaust emissions is based on current technology, resources and allowed costs only, but it does not mean that there is no emission.);

3) The reduced external social benefit of burial based on the substitution of burial by cremation. For example, the decomposition and organic circulation of soil will nourish the soil and help the growth of plants and animals; and balance of the climate;

4) The substitute of burial by cremation increases unnecessary energy consumption and arising of the temperature.

The external social benefit of burial:

1) The decomposition and organic circulation of soil, for example, will nourish the soil and help the growth of plants and animals; and balance of the climate;

2) Can collect or produce of gas;

3) Substitute the external social costs of cremation;

-   -   To avoid any unnecessary energy consumption and reduce the         emissions of carbon dioxide significantly;     -   To avoid influence of the surrounding environment and         acceleration of the global warming from high temperate;     -   To avoid worldwide air-pollution from cremation of organic         substances. Any kind of “standard of emissions” does not refer         to non-emission; it is only based on the use of technology to         reduce the pollution of emission.     -   Therefore, there are serious misallocation of social resources         in current burial and cremation.

To enhance the utilization rate of a cemetery, the Chinese Utility Model CN1827986A disclosed a fully closed and centralized cemetery comprised of an overground and underground portions, wherein the underground portion is a rectangular or circular air-tight burial chamber having a sealing cover, and a multi-layer modular setting support for placement of a plurality of urns or coffins; and the overground portion is comprised of a mounting base for the burial chamber and an identification tomb.

Chinese Utility Model CN1529027A disclosed a well type grave exclusively for placement of bone ashes, which is comprised of well pits of multi-layers, each layer of which could be partitioned into different regions for adaption to psychological need of peoples related to Feng Shui.

Chinese Utility Model CN101230760A disclosed a public cemetery and a funeral method; wherein the public cemetery is surrounded by plants and partitioned into several subareas in which drainage systems and water supply systems are arranged; wherein a management office is provided and a computerized and automated management is employed in the whole cemetery.
